A machine tool comprises a movable table 2 carrying a set of headstocks 11 having spindles 14 for holding rotating workpieces, the headstocks being brought by movement of the table each to different work stations 30, each work station having a power drive 32, 33 and coupling means for temporarily connecting that drive to a headstock brought to that work station, whereby each headstock takes its drive for the purpose of spindle rotation, from the work station with which it is temporarily associated. The headstocks 11 are mounted on a rotatable turret 2 surrounded by the work stations, but alternatively the headstocks may be moved linearly on a table. The drive for each of the spindles 14 comprises a motor 32 at each operating station which is coupled to a shaft, pulley and belt drive (24), (28), (29), (15) (Fig. 3, not shown) by means of an electromagnetic coupling, after each indexing movement of the turret 2. One half of the electromagnetic coupling (41) is fluid pressure retracted to provide adequate clearance during indexing of the turret 2. Each operating station may include guides and slides for supporting a non-rotatable tool for movement towards a workpieee in the spindle 14. Alternatively an operating station may include a rotary, spindle mounted, tool for operating with a stationary spindle 14. Screw cutting is also possible by advancing the spindle 14 under control of cams or a template. Each headstock 11 includes a lever 19 operated mechanism 21, 22, 18 for operating a chuck on the spindle 14.

Abstract: 1,251,663. Blowing lances. W. W. KAY. 16 May, 1969 [20 May, 1968], No. 23815/68. Heading F4B.  In a thermic lance for delivering oxygen comprising an outer casing 11 containing a plurality of mild steel rods 12, the rods are held firmly in position by the insertion of a plug at each end in the form of a hollow expandable rivet 15. The rivet when fixed in position forces the rods outwardly against the inner wall of the casing 11. The diameter of a washer 18 fitted to the rivet determines the size of the annular opening 19 receiving oxygen from an oxygen feed adaptor into which the lance is screwed at 13. Oxygen leaves the lance through a similar opening 19 at the opposite end.  In another embodiment (Figs. 3-6, not shown) the rods are forced radially outwardly by a maleable metal tube (23) passing through the centre of the casing and having zones of increased diameter along its length. These zones are urged outwardly against the rods by axially compressing a suitably crimped strip or wire (22) extending through the metal tube (23). In a further embodiment a plug in the form of a conical or frusto-conical member is driven into one end of the casing to force the rods radially outwardly.

Abstract: 1,265,560. Transistor frequency divider circuit. SINGER CO. 8 July, 1969 [12 July, 1968], No. 34353/69. Heading H3T.  A frequency divider comprises two crosscoupled transistors 10, 11, each biased in a single quiescently stable state of the circuit so as to conduct substantially the same current, an input terminal 32 for supplying an A.C. signal to the control electrodes of the transistors via two diodes 27, 28 which in the quiescent state of the circuit are D.C. biased for forward conduction, means storing electrical energy such as capacitors 35, 36 connected between an electrode 12, 13 of each transistor and a reference potential and an output terminal 34 coupled to an electrode 17 of one of the transistors for deriving an output signal. As shown, a positivegoing input causes both the transistors 10 and 11 to be biased off. Assuming that transistor 11 was the last to be conductive previously for a negative input, the charge on the capacitor 35 will be greater than that on capacitor 36 so that when the A.C. input signal goes negative again the transistor 10 will turn on. The positivegoing output from transistor 10 is coupled via RC circuit 25, 26 to cancel out the input negative signal to transistor 11 and reverse bias diode 28 so that the transistor 11 remains off. The next positive half cycle of A.C. input causes both transistors to be off. Then as the charge on capacitor 36 is now greater than that on capacitor 35 when the A.C. input goes negative, transistor 11 turns on, diode 27 becomes reverse biased and transistor 10 is held off. For very large inputvoltagea V1 the positive-going output may not entirely cancel out the input negative signal, in which case the transistor to which the positive-going feedback voltage is applied may conduct slightly (see I 2 , 38, Fig. 2, not shown). The circuit operates as a pulse frequency divider at frequencies in excess of 60 MHz.

Abstract: 1295973 Determining timing angle SCANS ASSOCIATES Inc 30 July 1970 [2 Sept 1969] 37030/70 Headings G1U and U12A6 [Also in Divisions Fl and G3]  The timing angle of an internal-combustion engine is determined by measuring digitally the time interval between the moment when the sparkplug of a selected cylinder fires and a predetermined position in the piston cycle of that cylinder. This is effected by counting pulses from an encoder 25, Fig. 6, driven by the engine crankshaft for the time between a pulse when a high voltage probe 21 detects the spark and a pulse on a magnetic pick-up 20 sensing a notch 18 in a crank-shaft vibration damper. The notch position is such that the pulse is produced when number 1 cylinder is at its top dead centre. The count may be compared with upper and lower pre-set limits either in digital comparators 40, 41 or after conversion to analogue form, in analogue comparators (42, 43,) Fig. 7, (not shown) to control delays 51, 52 via the contacts 54, 55 of which a servomechanism is operated to move a distributer adjustment lever 35 to correct the time angle. Conveyers bring engines to and from a loading and unloading bay to separate test stands Fig. 1, (not shown).
